Abstract
Introduction: Smoking cessation with an added tooth-whitening effect in nicotine replacement therapy (NRT) may increase motivation to quit smoking. The aim of this study was to evaluate the effectiveness of NRT-whitening agent in tooth stain reduction, being a motivational factor for smoking cessation among smokers.Materials and Methods: A pilot interventional study was conducted among thirty participants from June 2017 to August 2017. NRT-tooth whitening gum was distributed accordingly. Exhaled carbon monoxide (CO) was measured using CO breath analyzer, and extrinsic tooth stain score was assessed using the modified Lobene Stain Index at baseline, 2nd, 3rd, and 4th week. Analysis of intensity and area score for tooth stain, cigarettes consumption, and CO level comparison at baseline, 2nd, 3rd, and 4th week was performed using the Friedman test. Correlation between CO value and stain reduction value was performed using Pearson correlation test.Results: The difference in mean change in stain index scores, cigarettes consumption, and CO level between baseline and 4th week was statistically significant (P = 0.001). With regard to correlation between stain index score and CO value, statistically significant difference was found between total stain index value for lingual surface and CO value at 4th week(P = 0.00).Conclusion: The present study results provide evidence that the NRT-tested chewing gums can contribute to a better overall oral hygiene by removing the stain on the tooth surface, thereby motivate smokers to abstain from the habit.
